Principles of operating the Greenstar Plus Hybrid Manager ➊ Data is inputted into the FW200 controller • Calculation of system flow set temperature • The appropriate strategy is chosen – Strategy 1: Cost optimised ➌ Boiler: (the higher temperature heating option) • Supports central heating up to the calculated flow set temperature for the system or supports all DHW demand. Alternatively it can remain turned off.

Renewable Heat Incentive (RHI) Scheme for Domestic Properties Overview Who is eligible? The Renewable Heat Incentive (RHI) scheme for industry, The domestic RHI scheme applies to both off-grid and business and the public sector was introduced by the on-grid properties in England, Scotland and Wales. Government in November 2011 as part of its commitment to reduce the country’s carbon emissions by 20% by 2020.
Tariffs When discussing the RHI scheme with your customers, the first question you’ll probably be asked is “how much will I get and for how long?” What criteria are required to apply for the scheme? Training All installations must be carried out by an MCS approved Tariffs have been calculated by The Department of Energy installer and meet the relevant standards for each and Climate Change (DECC) and will change annually in-line technology.
